What is the most general way to list all the kernel tasks in a linux system?

Question

I am trying to figure out the best way to write a cross platform kernel code/shell script to list all the kernel task {(pid/tid , name)} in a linux dis. machine. it should be the most general possible. I tried to use ps -T but it is seems to be inaccurate and some platform don't support it in their busybox. Any suggestions?

Answer 1

If you want to distinguish user processes from kernel tasks, then this is a previous discussion on the subject: Identifying kernel threads

My answer to that question does not require any tools, it simply reads the contents of /proc//stat, so it should work on any distribution.
